1、一、阅读理解一、阅读理解 Many leading AI researchers think that in a matter of decades, artificial intelligence will be able to do not merely some of our jobs, but all of our jobs, forever transforming life on the earth. The reason why many people regard this as science fiction is that weve traditionally though
2、t of intelligence as something mysterious that can only exist in biological organisms, especially humans. But such an idea is unscientific. From my point of view as a physicist and AI researcher, intelligence is simply a certain kind of information processing performed by elementary particles (基本粒子)
3、 moving around, and there is no law of physics that says one cant build more intelligent machines than us in all ways. This suggests that weve only seen the tip of the iceberg and that there is the amazing potential to unlock the full intelligence that exists in nature and use it to help humanity. I
4、f we get it right, the upside is huge. Since everything we love about civilization is the product of intelligence, amplifying our own intelligence with AI has the potential to solve tomorrows toughest problems. For example, why risk our loved ones dying in traffic accidents that self-driving cars co
5、uld prevent or dying of cancers that AI might help us find cures for? Why not increase productivity through automation and use AI to accelerate our research and development of affordable sustainable(可持续的) energy? Im optimistic that we can develop rapidly with advanced AI as long as we win the race b
6、etween the growing power of our technology and the knowledge with which we manage it. But this requires giving up our outdated concept of learning from mistakes. That helped us win the race with less powerful technology. We met with fire and then invented fire extinguishers (灭火器), and we met with ca
7、rs and then invented seat belts. However, its an awful idea for more powerful technologies, such as nuclear weapons or super intelligent AIwhere even a single mistake is unacceptable and we need to get things right from the first. 1.How do many people feel about leading AI researchers predictions? A
8、.Worried.B.Curious.C.Doubtful.D.Disappointed. 2.What does the author think of intelligence? A.We know little about it.B.It belongs to human beings. C.It is too difficult to understand.D.We have a good command of it. 3.What does the underlined word upside in Paragraph 4 probably mean? A.Cost.B.Potent
9、ial.C.Quantity.D.Advantage. 4.Whats important for us in the race between people and technology? A.Learning from failure.B.Increasing our intelligence. C.Avoiding making mistakes.D.Making accurate predictions. Dogs are our best friends. Thats especially true after a disaster, such as an earthquake. W
10、hen buildings fall down, search-and-rescue dogs help find trapped people. Dogs amazing noses can pick up the smell of survivors. Now scientists have developed an electronic tool that does the same thing. Its taking smell detection(探测) to a whole new level. The new invention is a sort of electronic n
11、ose, which can detect extremely low levels of many compounds(化合物) from peoples skin. This isnt the first time engineers have developed such an object. Earlier models, however, have been bulky and expensive. They could not detect low levels of target compounds either. The new one is inexpensive and s
12、mall enough to fit inside hand-held equipment. The electronic nose can detect extremely slight smell of more than one compound at the same time. Being able to do this, in such a small object, is the significant discovery, says Sotiris E. Pratsinis, Professor of Process Engineering and Materials Scie
13、nce at the Swiss Federal Institute of Technology in Zurich. His team tested it in special spaces. They were like the small spaces where people might be trapped. Chemicals given off by the volunteers built up inside. The electronic equipment detected those compounds at unbelievably low levels. The re
14、sults were good news for the research team. But they may be not for our four-legged friends, who could soon be out of a job. Ideally, this technology could replace search-and-rescue dogs, Pratsinis says. Stephen Taylor, an electrical engineer, agrees that the new technology has some benefits over do
15、gs. Still, he thinks it may be too soon to have our trusty friends retire. He suspects, I foresee that such an object could add to the fine work done by the dogs. Taylor also points out some potential limitations of the new invention. E-noses are useful, but can be very likely to be affected by unst
16、able readings and interruption, he says. 1.Why does the author talk about dogs at the beginning? A.To catch the readers attention.B.To introduce the topic about e-noses. C.To show what search-and-rescue dogs do.D.To add background information for discussion. 2.Which of the following best explains bu
17、lky underlined in Paragraph 2? A.Complex.B.Fragile.C.Handy.D.Large. 3.What is Paragraph 3 mainly about? A.What e-noses working principle is. B.How e-noses are made. C.What differences between dogs and e-noses are. D.How powerful e-noses are. 4.What does Stephen Taylor mean? A.Dogs and e-noses could
18、work together.B.Search-and-rescue dogs will retire soon. C.E-noses are more reliable than noses of dogs. D.Dogs are better at finding out trapped people. Twenty-five years ago, most young Britons wanted a career in law, to be a doctor, or, if they were creative enough, to take up singing. But today,
19、 things stand different. According to a survey by Tesco Mobile, a UK company, the dream job of young people aged between 16 and 25 in the UK is a video blogger, or vlogger. The survey, carried out among 1,002 people, found that as many as 40 percent of them put vloggers as their number one choice on
20、 a list of ideal careers. This change is undoubtedly as a result of the Internet and social media. They have made it so much easier to reach the audience of the world, without having to enter a career in show business in the traditional way. In the past, the biggest stars were trained by the Hollywo
21、od studios; now, anyone with a computer camera can become a star. Vloggers are the big stars of today because they are normal people interacting(交流) with their fans about everyday life. However, what people see is only the bright side of being a vlogger and they fail to notice the fact that only tho
22、se who are successful earn fame(名声) and fortunes. For every success there are hundreds of others who never get off the starting line. There are the dreams that come true and the dreams that remain dreams forever. Although being vloggers is popular, some young people choose to follow careers that don
23、t necessarily earn them fame, but that allow them to make good use of the Internet to share their hobbies. Young Israeli David Leshaw, for example, runs a business called the Finishers Club. Its an online platform for runners to keep a record of their races. His job allows him to express his enthusi
24、asm, and is always a learning experience. And thats enough for him. 1. Why do more and more young Britons choose to be vloggers? A. Vloggers can earn greater fame and more money on the Internet. B. There is too much competition in the traditional show business. C. The Internet makes it convenient to
25、 enter show business. D. Anyone with a computer will surely become a star. 2. What can we infer from the fifth paragraph? A. Only a few vloggers can be successful. B. A vlogger cannot earn fame or fortunes. C. Being a vlogger is not a good career. D. Dreams will come true one day. 3. What do some yo
26、ung people like David do on the Internet? A. Learn from others.B. Become an online hit. C. Hold running races.D. Mix jobs with hobbies. 4. What is the passage mainly about? A. Most young Britons choose to be vloggers as their jobs. B. The Internet is influencing young Britons career choice. C. The I
27、nternet is taking the place of traditional studios. D. Young Britons cannot find jobs without the Internet. Four teenage girls from Minnesota, US. 120 hours of non-stop togetherness. No cellphones. This is not a reality show, but an adventure journey. It was really perfect, said Julia Ruelle of her
28、recent adventure to the Boundary Waters Canoe Area Wilderness with three of her childhood friends. By unplugging, we had an amazing time. Last year, the 16-year-old took part in an essay contest and carried off a prize. The award was a 5-day canoe and camping adventure with up to three friends. No p
29、arents or guides would be there. So Julia invited her friends Anna Wander, Madeline Wilson and Julianna Torelli. The four Minnetonka High School juniors arrived in Ely for training the day before they began the journey. They set out the next day at 7 a. m., quickly developing a routine. We were done
30、 paddling by noon, Julia said. We ate lunch at the campsite and then it was time for hammocks (吊床), reading, making friendship bracelets (手镯)and talking. The girls all had some experience in the outdoors before. Anna had been to the Boundary Waters with her family. I love how you are separated from
31、everything in your life, especially technology, Anna said. Without her phone, she said, Im less worried about things. Madeline, too, had been to the Boundary Waters a few years back. But this time, I had to paddle right and set up camp, she said. The girls made fire and cooked meal together. No one
32、was ever hungry or homesick, but they were nervous the final night as they waited out a thunderstorm. They left wet sleeping bags in one tent, and squeezed into another for the night. Every thunderstorm in the Boundary Waters feels huge, Julia said. On the car ride home, they were all on their phone
33、s catching up with friends. It was a little at a loss turning my phone on, said Anna. Mental health can be improved so much in the Boundary Waters. It really helps to get away and reconnect with yourself. 1.How did Julia Ruelle get the chance to camp? A.She won an essay contest.B.She was invited by
34、her friends. C.She performed well in her school.D.She asked her parents for support. 2.Why was the 5-day adventure unique to the girls? A.They needed to complete many tasks.B.They needed to find a guide on their own. C.They had to live on a boat for several days.D.They had to live without their smar
35、tphones. 3.What can we know about the girls from the story? A.They had not got any camping experience before. B.They all felt refreshed after the adventure journey. C.They enriched their learning experience by exploring. D.They used to keep in close touch with their friends by phone. 4.What did the

C.They reflected on their experiences.D.They didnt know what to tell their friends. 二、七选五二、七选五 With the development of science and technology, our daily life is becoming more varied and more convenient.
37、 At the same time, life in the late 21st century will be different from that nowadays, because many changes will take place then, but what will the changes be? _ There will be more and more people in the world and most of them will live longer than today. Computers will be much smaller and more usef

Traveling will be much cheaper and easier. _ _ More land will be used to build new towns and houses. Then there will be less room fo
39、r cows and sheep, so meat will be more expensive. Maybe no one will eat it every day. Instead they eat more vegetables and fruit. Maybe people will be healthier thanks to that. Work in the future will be different, too. _ Because of this, many people will not have enough work to do. This will be a p
40、roblem. A. The population is growing fast. B. Robots are most useful in the future. C. There will be changes in our food, too. D. Dangerous and hard work will be done by robots. E.
